MERIDIAN ATMOSPHERIC CIRCULATION (MAC) AND EXTREME RAINFALL IN NORTHERN MOROCCO

Abstract

During the last decades, Morocco is under the influence of a new predominant Meridian hemispheric Atmospheric Circulation (MAC). And according to its position in geo-climate between two systems climate more different in terms of the atmospheric conditions of a part, and its presence in the climate machine disrupted, which affect the normal state of the hydrological systems in our country. In the north, of cold valleys and disturbed, on the entire region of the North Africa and Western Europe. And South toward the poles by ridges warm and stable. Then the main objective of our work and attempts to explain the extreme precipitation in the northern Morocco. In the present work, we propose a double statistical methodology and dynamic and other interactive, has, for the period from 2010 to 2017
